When the ground width of a CPW is very narrow, the wave port should be modified for the ground plane to touch the edge of the wave port. So, first you draw small 2D rectangles that touch both the ground plane and wave port, and then you need to substrate these rectangles from the original wave...
I installed CST 2006 at a laptop which uses Intel(R) GM965 graphic chipset (Lenovo T61). When I opened a example file or created a new file, the computer is freezed, and the computer screen changes in very weird color. It seems that the graphic card is incompatible with CST, but I'm not sure. Is...
Varactor modeling in ADS
Dear,
I'm trying to model a varactor in ADS 2006 update3. I got SPICE model parameters from the data sheet of the varactor that I want to use.
First, I typed the value of the SPICE model parameters in DIODE model of ADS, but it didn't work. Moreover, I couldn't find...
A simple way to calculate the effective dielectric constant of a transmission line is to use the unwrapped phse of the S21. The phase of S21 is electrical length of the transmission line in degree. So, you can plot the effective dielectric constant versus frequencies by adding an expression of...
